    • For NMR peaks affected by the exchange process, the transient time (the time required for the exchange) is effectively zero; thus, as the exchange rate increases, the constituent peaks become broader and broader with no discernible shift in their positions. The inward shift (for the two-site case) becomes apparent only when the exchange rate becomes comparable to the difference of the original positions. Eventually a new band appears centered at the averaged position. IR bands, if affected by the pseudocollapse mechanism, show symptomatically not only broadening but also conspicuous inward shift (for the two-site case) immediately. See ref 9.
